Specification. forming part of Letters Patent No.il93,0 13, datedJuly 101877 papplication filed February 19, 18717.

To all whom it may concern:

Be it known that .I, AMBROSE M. SEARLS, of Geneseo, in the county ofHenry, and in the State of Illinois, have invented certain new anduseful Improvements in Pumps; and do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, mak-- The design of my invention is to lessenthe.

cost of submerged pumps, to render the same more efficient, and toenable them to be more easily and quickly placed in or removed fromposition; to which end it consists, principally,

in the peculiar construction of the pump-casing, substantially as andfor the purpose hereinafter specified.

It consists, further, in the means employed for combining thepump-casing with the discharge-pipe, substantially as and for thepurpose hereinafter set forth.

In the annexed drawings, A represents the barrel of my pump, which has aplain cylindrical form, is open at its upper end, and at its lower endis connected with and forms part of a valve-box, B, the lower end of thecentral opening in said barrel being in direct communication with thechamber b, between the inlet and outlet openings b and b, respectively.

Theinlet-opening b is formed within a side wall, b', of thevalve-box B,which has an upward and outward inclination of about sixty degrees froma horizontal line, and upon the inner face of said wall is placed around flat valve, 0, that is pivoted at its center to or upon one end ofa bar, D, the opposite end of which bar is hinged to a suitable support,d, at the-upper 'side of said opening I), the arrangement being such asto cause said valve to fall over and close the latter when not preventedby the inward flow of water.

As see in Fig. 2, the valve-box opposite to the inle opening b extendsoutward a distancenearly equal toithediameter of the bore of the barrelA, and within its outer face is provided with a valve-seat, 11, whichinclines upward and inward in a line parallel with the seat b', andincloses or contains the outer end of the outlet-opening b. A valve, 0,corresponding in all respects to the valve 0,. is in a like mannerhinged so as to enable it. by the force of gravity, to fall over andclose the opening b.

Surrounding the recess that contains the outlet-"alve and its seat-is an-shaped flange, B, which, preferably, incloses a square space, as shownby Fig. 3, and, when the pump is combined with a wooden pipe, E, isforced into the flattened surface of the same, so as to form awater-tight joint between said pipe and the space within said flange. Anopenin g, e, from said space into the interior of said pipe enableswater to pass into the latter from said pump.

The pump-casing and wooden pipe are combined by means of a metal strap,F, which passes around the latter, and has its threaded ends f containedwithin two lugs, G, that are secured to and project laterally outwardfrom the sides of the valve-box B. A nut, f, placed upon each of saidthreaded strap ends, in rear of said lugs, enables said strap to bedrawn inward with su'ificientforce to embed the flange B within saidpipe, and closely confine the latter and said pump-casing together.

The pipe E is closed at some point below the opening 6, so as to compelall water entering through the latter to pass upward.

Within the barrel A is fitted a plunger, H, which is solid, and isprovided within its periphery with a number of concentric grooves, h,which become filled with water, that operates as a packing for saidplunger. said grooves may be filled with rubber orany similar elasticmaterial.

The operation of the pump will be readily understood. At each upwardstroke of the plunger the inlet-valve 0 will be opened, and the interiorof the casing will become filled with water, while upon the downwardstroke of said plunger said inlet-valve will be closed, the outlet-valve0 opened, and said water will be forced into and through the pipe E.

The inclination given to the valve-seats en- If desired,

ables the valves to operate with greater ease and certainty than wouldbe possible were said valve-seats vertical or horizontal, there,

being less weight to lift and distance to be moved than in thelattercase, while the weight of said valves operates in a sufficient degree tocause them to automatically seat themselves.

In consequence of the manner of attaching the pump to the pipe, theformer can be easily and quickly changed when desired, so as to cause itto occupy a position nearer to or farther from the bottom of a well.

provided with the inclined valve-seats b and b, and inlet and outletopenings b and b, the whole forming one casting, substantially as andfor the purpose specified.

2. The means employed for combining the pump-casing with the pipe E,consisting of the A-shaped flange B, formed upon said cas ing, andcapable of being embedded w1th1n the side of said pipe, and the strap Ff, nuts I", and lugs G, or their equivalent, substan tially as and forthe purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this11th day of January, 1877.
